Filter by:Soft tissue sarcomas (STS) are a group of rare mesenchymal neoplasms affecting all ages. STS most commonly present as localised disease but despite surgery and adjuvant treatment more than half of patients will develop recurrent or metastatic disease. Leiomyosarcoma (LMS), a malignancy of smooth muscle, is one of the most common STS and undifferentiated pleomorphic sarcoma (UPS) is a common sarcoma sub-type with aggressive symptoms. Recent studies have demonstrated reasonable sensitivity of LMS to gemcitabine monotherapy with an objective response rate of 8-19%. However the overall survival is still only about 12 months which illustrates the critical clinical need for improved therapies for advanced STS and sarcoma in general. In this study the investigators propose to combine the immune synapse checkpoint inhibitor with the cytotoxic and immune modulating agent, gemcitabine. It is hoped that this dual immunomodulatory approach will enhance the effect of pembrolizumab on PD-L1 expressing LMS and UPS, leading to a safe treatment with patient outcomes. This is a two part, phase I, single centre dose escalation and dose expansion study in the total of 24 patients with newly diagnosed metastatic or inoperable LMS and UPS. There will be approximately 12 patients in the dose escalation cohort (part A) and the starting dose will be a fixed dose rate (FDR) gemcitabine of 800 mg/m2 on day 1 and 8 of 21 days cycles in combination of 200 mg of pembrolizumab given as an infusion on day 1 every 3 weeks. The MTD cohort (part B) will then be expanded to a total of 12 patients in order to further evaluate the safety and tolerability of that dose as well as to preliminarily assess response to therapy. The study is sponsored by Royal Marsden NHS Foundation trust and the funding for the study is provided by Merck Sharp & Dohme Limited.
This phase II trial studies the side effects of talimogene laherparepvec and radiation therapy and to see how well they work in treating patients with newly diagnosed soft tissue sarcoma that can be removed by surgery (resectable). Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Radiation therapy uses high energy x-rays, photons. electrons, or protons to kill tumor cells and shrink tumors. Giving talimogene laherparepvec and radiation therapy may work better in treating patients with soft tissue sarcoma.
This randomized phase II/III trial studies how well pazopanib, when combined with chemotherapy and radiation therapy or radiation therapy alone, work in the treatment of patients with newly diagnosed non-rhabdomyosarcoma soft tissue sarcomas that can eventually be removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Pazopanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether these therapies can be safely combined and if they work better when given together in treating patients with non-rhabdomyosarcoma soft tissue sarcomas.
This phase II trial studies how well depsipeptide (romidepsin) works in treating patients with metastatic or unresectable soft tissue sarcoma. Drugs used in chemotherapy, such as depsipeptide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
